How much ATF does a 6R140 take?
For the Ford 6R140, plan on about 13 quarts of ATF for a full fluid replacement, with the pan holding roughly 6.5–7 quarts. If you’re only draining and refilling the pan, you typically swap about 6.5–7 quarts. Always verify the exact figure for your specific model/year in the owner’s manual or a Ford service bulletin before starting.
Understanding the 6R140 and why capacity varies
The 6R140 is Ford’s six-speed automatic transmission used in many trucks and large SUVs. Its total fluid capacity includes the pan, valve body, gear train, torque converter, and cooler lines. The amount you drain and refill depends on whether you’re performing a pan drain-and-fill versus a full fluid exchange that includes the torque converter and cooler circuit. Accurate capacity is important to avoid running the transmission with too little oil or wasting fluid by overfilling.
Estimated ATF capacity values for common service scenarios
Below is a quick guide to what you’ll typically encounter when servicing the 6R140. Use these figures as a baseline, then confirm with your vehicle’s manual.
- Full capacity (including torque converter and cooler lines): about 13 quarts (roughly 12–13 liters).
- Pan drain-and-fill (drain the pan, not the converter or cooler): typically about 6.5–7 quarts.
- Full fluid exchange (a comprehensive flush that may include cooler lines and converter drain): about 12–14 quarts, depending on how aggressively you flush and how much is returned by the cooler circuit.
Note: Actual numbers can vary by model year, transmission pan design, and whether the cooler lines are flushed as part of the service. Always have a little extra ATF on hand to accommodate minor variances and to top off after the service.
ATF type and service tips
Choosing the correct ATF specification and following a proper service procedure helps protect the 6R140’s longevity. The Ford recommendation has commonly referred to MERCON LV for many 6R140 applications, but specifications can vary by year and vehicle. Always verify the current fluid specification in your owner’s manual or with a Ford dealer before purchasing or pouring.
- Use the fluid specification listed for your year/model (often MERCON LV). If your manual specifies a different specification (for example MERCON V in older iterations or newer equivalents), follow that.
- Replace the filter during a full service and ensure the pan gasket is in good condition.
- When performing a full exchange, consider flushing the cooler lines to remove varnish and debris that can affect shifting.
Concluding note: For a typical full-service replacement on a 6R140, having around 13 quarts on hand is prudent, with extra fluid available in case your first fill settles slightly high or you choose to flush more volumes through the cooler circuit.
Practical takeaways for owners
If you’re preparing to service a 6R140, here are practical guidelines to help you plan:
- Determine your service goal: pan drain-and-fill or a full system replacement/flush.
- Plan on approximately 6.5–7 quarts for a pan-only drain-and-fill, and about 13 quarts for a full replacement.
- Have extra ATF on hand (a quart or two beyond the calculated need) in case of minor overfill or additional purge during a flush.
In all cases, consult the vehicle’s manual for the exact capacity figures and use the specified ATF type. If you’re unsure, have a professional perform the service to ensure the correct amount is used and the system is properly filled and tested.
Summary
The 6R140 typically takes about 13 quarts of ATF for a complete replacement, with the pan itself holding roughly 6.5–7 quarts. A pan drain-and-fill will swap about 6.5–7 quarts. When planning a service, verify the exact specifications for your year and model, stock enough ATF, and consider flushing the cooler lines for a thorough job. Always use the ATF type recommended by Ford for your vehicle.
How much fluid does a 2011 f250 6R140 take?
Capacity: 6 speed Late Build 6R140 Total Fill 16.2 quarts. Capacity: 8.2 quarts Initial Fill.
How many quarts of transmission fluid does a 6R140 take?
The Ford 6R140 transmission has a total capacity of about 16.2 to 17.4 quarts for a full rebuild, but an initial fill after a filter change is typically around 8 to 10 quarts. When changing the fluid, you will need to add a specific amount based on whether you are just changing the filter or doing a complete fluid flush.

Fluid capacity breakdown
- Initial fill (with filter change): Approximately 8.28.28.2 quarts. Some sources say up to 101010 quarts.
- Total fill (full rebuild): Approximately 16.216.216.2 to 17.417.417.4 quarts.
- Service kit (filter, pan gasket, and fluid): Kits often come with 101010 quarts of fluid, which is usually the amount needed for a standard service.
Important considerations
- Fluid type: The 6R140 transmission requires MERCON LV Automatic Transmission Fluid (ATF).
- Service vs. rebuild: The difference in capacity is because a simple service only replaces the fluid in the pan, while a complete rebuild also includes the fluid in the torque converter and cooler lines.
- Deep transmission pans: Aftermarket deep pans can significantly increase fluid capacity, with some adding as much as 777 quarts to the stock pan.
- Transfer case: The transfer case on many vehicles with the 6R140 transmission holds approximately 222 quarts of the same fluid.

- Initial fill: This is the amount of fluid needed for a basic refill when the torque converter is not drained.
- Total fill: This is the capacity when the entire transmission, including the torque converter, is completely empty. It's best to add fluid in stages until the dipstick indicates the correct level, as the exact total can vary.
- Fluid type: The correct fluid for the 6R140 transmission is MERCON LV Automatic Transmission Fluid.
How many quarts of transmission fluid does a 6.7 powerstroke take?
The 6.7 Powerstroke transmission fluid capacity varies by model year, but it is approximately 16.3–17.4 quarts for the 6R140 6-speed (2017-2019) and 18.2 quarts for the 10R140 10-speed (2020-2025) when performing a dry fill. A basic drain and fill typically requires about 8 quarts of fluid for the 6R140 transmission.
6R140 (6-speed automatic)
- Dry fill capacity: 16.3–17.4 quarts
- Drain and fill capacity: Around 8 quarts
- Fluid type: Mercon LV
10R140 (10-speed automatic)
